A nebulizer (nebuliser) is a device that allows liquid particles attached to a vibrating element to be nebulized by vibration to form a mist that can move with the air stream. For example, the nebulizer may be a device that provides a patient with a mouth, and the liquid particles may be a medicament that is nebulized and delivered to the human body. The atomizer can also release the medicament by controlling the energy (vibration frequency, vibration intensity (amplitude)) and time of vibration, so that the atomizer can accurately release the medicament in each use, and accurately administer the medicament with the dosage of effective curative effect to patients, thereby reducing the medicament waste and risk caused by overdose. The specification discloses a method and a circuit system for driving an atomizer, which are capable of determining the atomization time of the atomizer through an audio signal, so as to achieve the purposes of effectively avoiding waste and accurately releasing an atomized substance (such as atomized medicament particles).
Fig. 1 and 2 show a schematic cross-sectional view of an embodiment of a nebulizer.
The main structure of the atomizer 100 includes a breathing member 10, which is provided with a mouth portion 11 contacting with the mouth of a user to form an atomizer outlet of the atomizer 100, the breathing member 10 is sleeved at the outlet of the atomizer 100 where the generated atomizer is released, such as a split-flow chamber 12 shown in the figure, the split-flow chamber 12 is arranged in front of an air inlet region 1131 and an air outlet region 1132 of the atomizer 100, the front is connected with the breathing member 10, the rear is sleeved on a joint end 113 of the atomizing chamber 15 and the air outlet chamber 16 in the atomizer 100, and the split-flow chamber 12 is used for splitting the passing air flow, for example, the air suction and the air exhaust of the user can be split.
A diverter baffle 13 is disposed on the air inlet region 1131 of the portion of the atomizing chamber 15 adjacent to the respiratory member 10, the diverter baffle 13 separating the atomizing chamber 15 from the diverter chamber 12, and the structure of the diverter baffle 13 includes perforations 121 for providing unidirectional air flow therethrough. The exhaust chamber 16 is provided with an exhaust port 114 at the other end, except for an exhaust region 1132 adjacent to the respiratory member 10, and includes an exhaust valve sheet 14 for controlling unidirectional air flow to exhaust the air flow in the exhaust chamber 16. The other end of the atomizing chamber 15 is provided with an air inlet structure, and the main structure is an air inlet valve plate 17 and an air inlet 112 for controlling unidirectional air flow.
The nebulizer 100 is provided with a nebulizer section 115 for forming a medicament into a nebulizer, wherein a nebulizer generator (aerosol generator) is provided and driven by a control circuit, and the nebulizer formed by the nebulizer section 115 is discharged into the nebulization chamber 15 through the nebulized liquid inlet 111.
In the nebulizer 100 shown in fig. 1, the airflow sequentially passes through the air inlet 112, the air inlet valve plate 17, the nebulization chamber 15, the air inlet region 1131, the perforation 121 of the diversion baffle 13, the diversion chamber 12, and the mouth 11 of the respiratory component 10 to form a first airflow F1, which may be referred to as an inhalation phase (inhalation phase), and is shown as an airflow formed when the mouth 11 of the user inhales, and this first airflow F1 may inhale the nebulized material in the nebulization chamber 15 into the user.
In the nebulizer 100 shown in fig. 2, the second air flow F2 is formed by sequentially passing through the mouthpiece 11 of the breathing member 10, the split-flow chamber 12, the exhaust region 1132, and the air flow exhausted from the exhaust valve plate 14 through the exhaust port 114, and this may be referred to as an exhalation phase (exhalation phase), where the second air flow F2 is formed when the user exhales while holding the mouthpiece 11, and at this time, the second air flow F2 does not bring the aerosol into the user.
In particular, according to the method of driving the nebulizer according to the present invention, the example shown in fig. 1 and 2 shows that the sound signal generator 101 and the sound signal receiver 102 are disposed in the breathing member 10 of the nebulizer 100, and the drawings are only for illustration, and may be integrated with each circuit module in the nebulizer 100 during actual operation. According to one embodiment, the sound signal generator 101 is a device or structure, such as a reed or a sounding structure, capable of generating an audio signal within a predetermined frequency range by a specific direction of airflow (e.g., the first airflow F1). The sound signal receiver 102 is configured to receive sound signals generated by various environments, and further includes a sound signal generated by the sound signal generator 101, from which an audio signal can be obtained.
The sound signal generator 101 is capable of being driven by the airflow in the atomizer 100 to generate an audio signal within a specific range, and can be separated from other frequency signals generated by the environment, that is, the circuit system in the atomizer 100 can be driven to generate the atomized matter according to the audio signal. It should be noted that, the sound signal generator 101 adopts a specific device or structure, which is designed to enable the airflow in a single direction to generate a sound signal and generate a specific audio signal; conversely, the other direction of air flow may not generate an acoustic signal or generate an undesired frequency signal. Furthermore, the sound signal receiver 102 may be operated in conjunction with volume information in the sound signal, for example, the sound signal with sufficient energy may be operated by the circuitry to drive the atomizer to operate according to the sufficient volume information.
In another embodiment, the sound signal generator 101 is not necessary, but the sound signal receiver 102 may only receive sound signals generated by various environments (including internal air flow), and then the control circuit in the circuit system converts the sound signals into audio signals, and then determines whether the audio signals are signals within a default frequency range.
Still further embodiments provide a receiver that receives only audio signals in the default frequency range, i.e., other ranges of audio signals other than audio signals in the default frequency range are not received and do not drive any action, so when the audio signal receiver 102 receives audio signals in the set range, the control circuit of the atomizer 100 drives the atomizer generator to generate the atomized objects.
It is mentioned that the atomizer disclosed in the specification uses the sound signal as the basis for judging whether to drive or not, and the audio information in the sound signal, that is, the frequency of sound vibration, can be obtained from the sound signal through signal processing, and the threshold is set according to the design of the adopted sound signal generator, so that the circuit system can drive to generate the atomized matter only when receiving the audio signal within a specific range. In addition, the information of the sound volume can be obtained from the sound signal, the sound volume represents the amplitude of the sound signal, and the amplitude and the sound volume are positively correlated, so that the breathing force of the user can be judged according to the sound volume, and the circuit system also sets a threshold according to the information, and can be used as a reference basis for driving and generating the atomized matters.
According to an embodiment, the circuit system for implementing the method for driving the atomizer 100 is disposed in the atomizer 100, and the circuit system can determine whether to use the sound signal generator 101 according to the requirement, and the audio signal provided by the sound signal generator 101 can be separated from the general environmental sound signal to avoid malfunction. Alternatively, the audio frequency range that can be received by the sound signal receiver 102 is also controllable to distinguish sound signals of a general environment. For example, the circuitry is configured to determine whether the default frequency range for driving the aerosol generator is a normal frequency range audible to the human ear or a supersonic frequency range inaudible to the human ear.
Fig. 3 is a schematic diagram of another embodiment of the atomizer 30, which is not intended to limit the scope of the invention, and the pattern and arrangement of components may be adjusted according to actual requirements.
The components for driving the atomizer to operate mainly include a sound signal generator 302 and a sound signal receiver 303, which are connected to each other, wherein the sound signal generator 302 disposed on the breathing member 31 may be various structural components or circuit components for generating specific sound signals (frequency or amplitude) according to air flow, and the sound signal receiver 303 disposed on the control circuit board 301 in the device main body 32 may be implemented as a circuit module or software module, and the sound signal receiver 303 may be connected to a control circuit of the device and may be disposed on the control circuit board 301 for converting the sound signals generated by the sound signal generator 302 into audio signals or volume signals as a basis for driving the atomizer 30 to operate.
In operation, the sound signal generator 302 disposed in the breathing member 31 can operate according to the air flow of the user's exhaling or inhaling, especially in the action of inhaling to obtain the atomized material, the sound signal generator 302 generates the sound signal according to the air flow, and transmits the sound signal to the sound signal receiver 303, and the sound signal receiver 303 cooperates with the control circuit to generate the audio signal and/or the volume signal.

In the method for driving the atomizer, after the sound signal receiver receives the sound signal, the control circuit determines whether the audio signal is within the default frequency range, if the audio signal is within the default frequency range, the driving circuit generates a vibration signal, and drives the atomizer generator, especially drives the vibration component 42 to generate a vibration wave with a specific frequency, so that the object (such as liquid particles) on the perforation component 43 is vibrated out (atomized) by the vibration wave in a vibration manner, and forms an atomized object in the atomization portion 115 in cooperation with the device shown in fig. 1, and is discharged into the atomization chamber 15 through the atomized liquid inlet 111, and then is sent into the user along with the first air flow F1.
According to an embodiment, when the atomizer is in operation, the sound signal generator may be disposed on a path of the airflow in the atomizer, such as a portion contacting the mouth of the user, the sound signal generator is designed to generate a specific frequency and a sound volume, the frequency is a main judgment condition, the sound volume is the next time, the sound signal generator is a whistle, a dog whistle, a reed, etc., the sound signal receiver is a microphone, for generating an audio signal after receiving the sound signal, and the device may be designed to receive only the sound signal in a specific frequency range.
One embodiment of circuitry for driving the generation of the aerosol may be seen in fig. 5, which may be contrasted with the sound signal generator (101, 302) and sound signal receiver (102, 303) shown in fig. 1, 2 and 3.
The atomizer is provided with a sound signal generator 501 and a sound signal receiver 502 on a path through which the air flow passes, the sound signal generator 501 generates a sound signal along with the air flow, and the sound signal generator 501 can be designed to generate a sound signal of an audio signal in a specific frequency range. The sound signal receiver 502, such as a microphone, may be disposed in the path of the airflow in the atomizer, and may be designed to receive various frequencies according to requirements, for example: a sound signal of a frequency audible or inaudible to the human ear.
The circuit system is provided with a control circuit 503, which is electrically connected with the sound signal receiver 502 and the atomizer generator (driving circuit 507) for controlling the operation of the atomizer, and comprises determining whether to drive the atomizer generator to generate the atomizer according to the audio signal in the sound signal, particularly, driving the vibration component 508 by the driving circuit 507 to generate vibration waves so as to atomize the object therein. The control circuit mainly controls the operation of the whole atomizer, so that when the atomizer is driven to operate, the atomizer can be driven according to the audio and volume information generated by the inhalation and the emetic of a user, the starting operation time of the atomizer generator can be adjusted according to the situation, and time delay can be properly given.
The method of driving the atomizer can be referred to as the main flow embodiment shown in fig. 6.
Initially, in step S601, a sound signal receiver disposed in the atomizer receives a sound signal, which may be from an external environment or an air flow flowing in the atomizer. In step S603, the audio signal can be obtained by converting the audio signal processing program in the control circuit, then, in step S605, the program in the control circuit compares the default frequency range according to the obtained audio signal, and if it is determined that the default frequency range is met (yes), in step S607, a driving signal is generated to make the driving circuit drive the atomizer to operate, such as sending a voltage to the vibration component, so that vibration waves are generated to the perforation component to atomize the object on the perforation component, and an atomized object is generated. If the audio signal is not within the default frequency range (no), the circuitry discards the information in step S609, and the process continues with the subsequent process of receiving the audio signal in step S601.
Through repeating the steps, the atomizer continues to operate according to the air flow generated by the respiration of the user.
Fig. 7 shows an embodiment of a method flow for driving a nebulizer in a nebulizer using an audio receiver designed to receive a specific frequency range, such an audio receiver being capable of actively rejecting sound signals outside the system set audio signal range by filtering techniques. In step S701, when the audio receiver receives the audio signal within the preset range, the control circuit is notified, in step S703, to directly drive the atomizer to operate without judgment.
In the exemplary embodiment of the method for driving a nebulizer shown in fig. 8, the volume information is introduced in this procedure, and initially, in step S801, the sound signal receiver receives the sound signal, in step S803, obtains the composition of the audio signal from the sound signal after signal processing (e.g., fourier transform), and in step S805, obtains the volume information in the sound waveform.
Then, in step S807, the control circuit determines whether the sound signal received at present meets the audio and/or volume conditions according to the preset threshold (frequency threshold, volume threshold), the determination conditions may refer to the audio and the volume at the same time, or determine whether to drive the atomizer to operate according to the audio information only in the above embodiment, and in still another embodiment, the device may perform the determination according to the volume only. If the audio and volume conditions are referenced simultaneously, including determining whether the audio signal is within the default frequency range and the volume is greater than the preset threshold, if both the audio signal and the volume meet the threshold (yes), step S809 is performed, the control circuit generates a driving signal to enable the relevant driving circuit to drive the atomizer to operate; otherwise, if either the audio or the volume does not meet the designed threshold (no), the control circuit ignores the information in step S811, and the process returns to step S801 to re-receive the audio signal and acquire the audio signal.
In step S807, if only the volume is used as the determination condition, the volume can be used to determine the breathing force of the user as in the above embodiment, so that the circuit system can compare the threshold and determine whether to drive the atomizer to generate the atomized matter, if yes, in step S809, the atomizer is driven to generate the atomized matter; otherwise, it indicates that the sound volume does not reach the threshold, in step S811, the atomizer is not operated.
Through repeating the steps, the atomizer continues to operate according to the respiration of the user.
Taking the mouth breathing of the user as an example, in the inhalation stage, if the atomized medicament in the atomizer is inhaled intentionally, the user should inhale with a force, so that the airflow flowing in the atomizer is driven to have a certain energy (flow rate), so that the sound signal generator generates a sufficient volume or amplitude and is received by the sound signal receiver, namely, the relevant circuit is driven to operate; conversely, if the user does not inhale unintentionally, or during the exhalation phase, or if the outside air flow enters the atomizer, the threshold is set so that the volume is insufficient to drive the atomizer, thereby eliminating the situation of improper driving.
Furthermore, if the volume is used as the basis for driving the atomizer, the amplitude (size) of the volume can be referenced, and if the volume is large, the circuit system can generate more atomizers by controlling the vibration component, so that the output rate is improved; if the volume is small, but still exceeds the set threshold, relatively less aerosol can be provided, resulting in a dynamic dosing adjustment.
An example of the manner in which the atomizer is driven is described in fig. 9, which can determine the energy required to drive the vibrating element therein based on the volume level.
In step S901, the control circuit obtains the sound signal from the sound signal receiver and obtains the volume information therein, and in step S903, the volume information may obtain a corresponding electrical information according to a default condition. For example, a table may be set, in which a plurality of operation modes are recorded, including a plurality of volume amplitudes greater than a default threshold corresponding to a plurality of driving voltages, respectively, and each volume amplitude corresponds to a driving voltage, so as to form an operation mode. The look-up table is stored in a control circuit of the atomizer. In step S905, after the control circuit obtains the volume information and compares the volume information with the table, a driving signal corresponding to a specific driving voltage is determined, in step S907, so that the driving circuit can drive the atomizer according to the driving signal to dynamically adjust the output rate of the atomized matter.
The flow shown in fig. 9 can be matched with the flow embodiment shown in fig. 6 to obtain the audio and the volume information at the same time, and the volume can be used as the basis for determining whether to drive the atomizer or not, and can also be used as the basis for determining the operating mode of the atomizer. The embodiment of fig. 7 may also be used to automatically filter out sound signals outside the default frequency range when the sound signal receiver is designed to receive a receiver with a default frequency range, and may also be used to determine that the atomizer can be driven to operate under a condition of large enough volume.
In summary, according to the above embodiments of the method and related circuitry for distinguishing between the nebulizer, the nebulizer may provide the user with inhalation of the nebulized medicament, for example, when the user's mouth contains the respiratory part of the nebulizer, the airflow generated in the nebulizer includes the airflow caused by inhalation and exhalation during the operation of the breath, so that the nebulizer may generate an audio signal (or volume) by using the inhalation airflow to drive the nebulizer; or the jetting air flow is utilized to generate an audio signal for turning off or not driving the atomizer generator, so that the atomizer can be driven more effectively and the waste generated by continuous operation can be avoided under the condition that the atomizer is not needed.
The above disclosure is only a preferred embodiment of the present invention and is not intended to limit the claims of the present invention, so that all equivalent technical changes made by the application of the specification and the drawings of the present invention are included in the claims of the present invention.
